SPECIFICATION forming part of Letters Patent No. 610,148, dated August30, 1898. Application iiled December 15, 1897. Serial No.. 662,038. (Nomodel.)

To all whom t may concern.-

Be it known that I, JAMES DRoMMoND SoHo- FIELD, a citizen of the UnitedStates, residing at Dallas, in the county of Dallas and State of Texas,have invented certain new and useful Improvements in Cultivators; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in cultivators of the straddle-rowor sulky style.

The main object of my invention is to produce a new and improvedcultivator of this class, the same being generally improved in regard toits structure and various details, all as will hereinafter appear, andwhich is also arranged, constructed, and adapted to combine with variousstyles and arrangements of cultivatorshovels, whereby it is adapted forvarious kinds of cultivation, as may be dictated by the character of thesoil, locality, and vegetation to be cultivated, and also tosimultaneously open furrows and plant and cover seed of various kind,whereby by its presence the farmer is enabled to follow various kinds ofagricultural pursuits with the single machine and its attachments.

Various other objects and advantages of my invention will hereinafterappear, and the novel features thereof will be particularly pointed outin the claims.

Referring to the drawings, Figure l is a perspective view of acultivator embodying my invention, the saine being shown as forcultivating corn, cotton, dac. and as provided with what I term a Texasgang, so named because of its popularity and particular adaptation inthe State of Texas and vicinity. Fig. 2 is a longitudinal sectional viewof the same. Fig. 3 is a 4perspective view of the planter attachmentthat may be employed in connection with the cultiVator-frame for thepurpose of transforming the machine into a planter for successfullyplanting in rows or drillscotton, corn, sorghum, duc. Fig. 4 is asimilar view of one member or section of what is popularly known as aWestern gang, so named because of its popularity in most of the WesternStates, and which, in conjunction with its companion, maybe attached tomy cultivator-frame. Fig. 5 illustrates in perspective the disjointedparts composing the springstandard support and its socket andthe partupon which it is formed. Fig. 6 is av per spective View of one of theswinging adjustable seat-bars and its adjustable block. Fig. 7 is aperspective view of one of the braces employed between the head-blocks,side bars, and cranks of axle. Fig. 8 illustrates in perspective thedisjointed parts composing the front brace and the adjustable couplingfor connection thereto for adjusting the draftpole. Fig. 9 is aperspective view of the rear end of one of the side beams and partssupported thereby. Fig. lOis a plan view of the cultivator-irame. Fig.1l is a transverse section of the same immediately in advance of thefront transverse brace. Fig. 12 is a transverse section through one ofthe head-blocks. Fig. 13 illustrates in side elevation the disjointedmembers composing the beam-clevis.

The two ground-wheelsl may be journaled on the lower journals with whichthe two independent cranksections 2, composing the crank-axle, areprovided and in which they terminate at their outer ends. Between theircranked portions the two crank-sections are connected by acoupling-sleeve 3, so that the two crank-sections, and therefore thegroundwheels, may be adjusted in and out, the axlen sections beingsecured in any of their relative adjustments by means hereinafterdescribed or otherwise.

The two side beams 4: may be and preferably are formed of metal. Thesetwo side beams 4 converge toward their front ends and areformed withinwardly-disposed rear terminals, formed integral with each of which isan eye 5, which forms the coupling by which the sleeve 3 and the axle 2may be secured to the side beams. Set-screws 6 may enter each eye 5 andserve to secure the axle-sections in their adjusted positions.

IOO

minate in a hook for engaging with the liftchains I0, that are in theusual manner connected to the cultivator-beams hereinafter referred to.Each of these lifting-levers is furthermore provided with an ordinaryform of spring-actuated locking-pawl for engagement with theadjacently-located toothed lockingsector 7.

The support for the seat I1 for the driver or operator in this instanceconsists of two seat-bars 12, which are bolted or otherwise securedtogether at their rear ends and are gradually diverged toward theirfront ends, at which latter points they are pivotally bolted, as at 13,to short inwardly-disposed standards 14, secured to the side beams 4 ofthe cultivator-frame. AsperhapsbestillustratedbyFigs. 6 and 10, it willbe seen that each seat-bar 12 is provided with a sliding sleeve 15, onthe under side of which is formed a stepped or notched flange 16, thesteps or notches of which are arranged in different planes. By adjustingthese sleeves 15 similarly on the seat-beams, so as to cause thedifferent steps or notches to be brought above and in supportingposition upon the coupling-sleeve of the rear cranked axle, it will beobvious that the seat 11 will be vertically adjusted to suit the driveror operator. The front ends of the seat-bars being pivoted at 13 permitsof the seat and its supporting-bars to be swung forward and over uponthe machine when not in use and the machine is used as awalkingcultivator.

Attention is now directed more particularly to Figs. 8 and 10. The twoside beams 4, it will be observed, converge and at their front endsembrace the opposite sides of a draftpole 18, at which point a pivotalconnection is effected by a transverse bolt 19, such connection being atsome distance in advance of the rear end or heel of the pole. Securelybolted to the rear end or heel of the draftpole is a metallic heel-plate20, the same being of such shape as to lit snugly the end, bottom, andopposite sides of the pole. Formed integral with the rear wall of theheel-plate is a vertical flange 21, the same being provided with aseries of holes 22, any one of which may be bolted by a bolt 23 to apair of perforated ears 24, that project forward from the cross-bar 2-5,that is interposed between the side beams 4, immediately in rear of thedraft-pole. The cross-bar 25 is concaved on its under side to receivethe arched draft-yoke 26 and is provided with perforated ears 27,through which clips 28 are passed for securing said draft-yoke inposition. The opposite ends of the cross-bar have cast thereon angularend securing-plates 29, which bear against the inner faces of the beams4 and are bolted thereto. It will be obvious that by removing the bolt23 the draft-pole may be tilted or adjusted to any height desired andthe cultivator-frame always remain level, which is most desirable.

In Fig. 5 I have illustrated in detail an angular casting 30, one ofwhich is located on each beam 4. These castings are bolted to the beams4, and depending from each casting is a depending sleeve 31, each sleeveembracing one of the terminals of the yoke 26. These sleeves arestrengthened by inclined braces 32, located between the sleeves 31 andthe castings 30. The castings 30 are also formed each with a verticalsocket 33, and in each socket is removably seated a curved standard34,i"rom the upper outwardly-curved end of which depend hooks 35, ineach of which is supported one of the pair of beamsupporting springs 36.

The ends of the arched yoke 28 are outwardly disposed each to looselyreceive a cylindrically-bored head-block 37, in the opposite ends ofwhich bored cones 38 are located. Pins 39 may be passed through theextremities of the arched draft-yoke 28 for the purpose of securing thehead-blocks and their cones in place.

Inclined brace-rods 40 are bolted at their upper ends to the side beamsand at their lower ends receive the outer cones 38. Clips 41 may belocated in the brace-rods 40, and similar clips 42 may be located oneach of the cranked axle-sections, those clips 40 and 41 at the sameside of the machine being connected by intermediate braces 43, pivotedat their ends to the clips, so that a direct draft applied to thehead-blocks is transmitted to the frame or side beams 4 and axles, andthe pivotal connection mentioned permits of a relative adjustment of theground-wheels.

The head-blocks 37 are provided at their front sides with the verticalflanges 44, perforated to receive the draft-chains 45, which at theirfront ends are connected to the usual loosely-suspended draft-links 46,that hang from the doubletree 47, pivoted upon the draft-pole. Thesedraft-links are provided each with a series of holes,and removably andtherefore adjustably connected thereto are the two singletrees 48.

Any style of cultivator-beams-as, for instance, that shown in Figs. 1and 2 and indicated as 49-may be connected by the usual coupling 50 tothe head-blocks, and the same may be either flat or pipe style, aspreferred, and providedwith anypreferred number and arrangement ofshovels. In Figs. 1 and 2 I have illustrated what I term the Texas gang,so named by reason of its popularity in that State. Again,in Fig. 4 Ihave illustrated and indicated by 51 what I call the Western gang, sodesignated for its popularity throughout the West. The numerous styles,however, may be varied at will, and I have merely illustrated two,because they are those most generally used. In any case it wil-l beapparent that aready connection may be effected to the head-blocks bymerely removing and replacing the clevis bolts 52. The lifting-chains 10are then connected, as

IOO

are also the lifting-springs 36, to the stirrups 53.

In addition to employing this machine as a ouitivator, I alsocontemplate employing the same as a one or a two row planter of thelatest type.

Referring now more particularly to Fig. 3, it will be seen that I haveillustrated in detail a two-row-planter attachment. In said figure, 55designates a pair of compound beams having front inwardly-disposed ends56, to which are connected the clevis members 57 for coupling with thoseof the cultivator frame. Each compound beam 55 is spread at its rearend, as at 58, and at its juncture supports a shovel-carrying standard59 for opening the furrows. Any style of planting mechanism may besupported on each beam; but in the present instance I have illustratedone style of my disk planter. A doubly compoundly curved yoke 60 isbolted to the rear spreading terminals of each beam 55 and is in turnsupported bythe covering-disks Gl. Through suitable gearing operated bysaid disks and contained in the gear-case G2 motion is imparted to thefeedshaft G3 and to the feed mechanism (not shown) contained Within thehopper 64. For the purpose of regulating the distance apart of theplanted rows I may provide any means for accomplishing this object. Inthis instance I connect the two-beams 55 by overlapping bars 65, towhich I attach the draftchains IO. These bars are perforated and adjustably secured together by bolts G6.

It is thus apparent that I have produced an agricultural apparatus ormachine which, under the general name of cultivator, is adapted bysimple means to be transformed into a machine for cutting stalks, a fouror six shovel gang-cultivator, or a single or double row planter. It isfurther apparent that by adjusting the draft-pole up or down the machineis adapted to operate in conjunction with any shovel sweep or gang, willrun lightly regardless of weight of operator, and is readily adjustableio entirely relieve the horses necks.
